    Have a bunch of M2TS files just ripped from BD. Would like to convert to
    MKV to save space and retain quality. Are there any user friendly freeware
    converters to do the job? Thank you, Jon

    If, by "save space and retain quality," you mean recompress the x264,
    the two goals are mutually exclusive. I suppose it's possible to
    reduce image quality to the magical mystery point where you personally
    can not tell the difference from the original, but all this seems to
    fly in the face of Einstein's theory on time-space, to wit: you have
    to waste inordinate amounts of the former in order to achieve a
    reduction in the latter;-) And then, what do you have? Certainly not
    Blu-Ray.

    That's not to say that all Blu-Ray discs are created equal (in image
    or sound quality) to begin with, but I doubt that you'll come up with
    a formula to handle each case without personal trial and error,
    further exacerbating this time-space lack-of-continuum.

    Here's an alternative idea for saving space: discard the protective
    plastic cases and save the discs in sleeves. On another hand, if you
    don't intend to keep the discs, then 50 or more exact images would
    probably fit on a 48 cubic inch, 2 TB drive ($80 at Amazon). That
    would be a dramatic reduction in space (though very much less so, when
    compared with the sleeve idea) without any sacrifice of quality.

  4. I had the same task a couple of weeks ago and came across MakeMKV. Whether
    it's freeware or not perplexes me, however. I came across some instructions
    at their site that says when the demo expires after 30 days, just redownload
    and it will work again so I don't know. It is extremely easy to use though
    and I'm finding about a 50% reduction over original BD file size. HTH

    There are good ones, but not just one. There is no DvdShrink for
    BDVD.
    It requires about 100gb of space to create a 4gb output portable .mkv
    file.

    1) TSMuxer and TSMuxer GUI to demux the m2ts files into individual
    audio/video/subtitle/chapter streams

    2) Eac3to to convert DTS audio into AC3. (Madshi has a gree GUI for
    eac3to)

    3) BdpSup2Sub to convert .sup subtitles to .idx/.sub format (optional)

    4) MKVToolnix MKVMerge GUI to create a .mkv of the video/chapter and
    converted audio/subtitle streams

    5) Handbrake to convert the .mkv to .mkv (h264) format.
    To reduce the space of the output select 1280 or 823 for new widths
    to convert
    1080P to 720P or 480P
    There is a burn subtitles into the output option for videos with
    seperate subtitle streams integral to the
    dialog.
    There is a size output that can be set for max size. Select 3900
    for 720P or 2000 for 480P for a 3.9or 2.0 gb file that will fit on
    FAT32
    devices such as a portable thumb drive.

    The new .mkv can then be played on certain BDVD players or on PC using
    a program such as Media Player Classic.

    Most can see no difference between a 4gb 720P and a 20gb 1080P on a
    60" display from a comfortable sitting distance.

    One can make a larger than 4gb .mkv and then split it into two two
    parts with MKVMerge GUI.

    Here is a good thread to read:
